BLOWPIPE.

. SPECIFICATION forming part of Letters latent No. 617,729, datedJanuary 17, 1899. Application filed March 11,18 ,8. Serial lio- 678,505.(No model.)

To all whom it may concern:

Be it known that I, WILLIAM S. FILLEY, a citizen of the United States,residing at Montpelier, in the county of Williams and State of Ohio,have invented new and useful Improvements in Blowpipes, of which thefollowing is a specification. I

My invent-ion relates to blowpipes in which carbureted air is employedboth as the medium for producing the flame and as the jet fordirectingthe flame and concentrating the heat upon any particular point; and theinvention consists in the novel construction and combination of partshereinafter fully described and claimed.-

In the accompanying drawings, Figure 1 is a longitudinal sectional viewof a blowpipe constructed in accordance with myinvention. Fig. 2 is ahorizontal section on the line a: :r, Fig. 1.

In the said drawings the reference-numeral 1 designates a handle,of anysuitable material,

having a central recess 9, in which is located a vertical tube 3,secured in place by a screwthreaded socket 4, fitting on the upper endof said handle. Intermediate its ends said tube is formed with a lateralpipe 5, the outer end of which is provided with a hose 6, connected withany suitable carbnreting-niachine. Said pipe near its inner end isconnected by an in clined passage 7 with a valve-casing 8, parallel withthe pipe 5, but extending beyond the opposite side of tube Thisvalve-casing is connected by a passage 9 with a Bunsen or other burner10 and at its lower end is formed with holes 11 for the admission ofair. This burner may be of any ordinary construction, and a detaileddescription thereofis notnecessary. Located in said casing is aneedlevalve 12 for opening and closing communication between the sameandthe passage 9. At the outer end the-casing is provided with ascrew-threaded cap 13, through which passes the outer end of theneedle-valve, provided with a hand-wheel 14. Said needle-valveintermediate its ends is screw-thrczuled to enengage with conrespondingserew-rhrcads in the end of said casing.

The numeral 15 designates a packingwing interposed between the end ofthe casing and the cap 13.

The numerals 16 and 17 designate r'eniovable screw-plugs engaging with.threaded holes in the casing S and passage 9.

Located in the tube 3 is a verticalLv-mov- 5 5 able rod 18, provided atthe upper end with a stem 19, to which is secured a cylindrical valve 20for opening and closing communication between said tube and the pipe 5.Located on said tube is a vertically-movable 6o collar 21, provided witha thumb-screw 23, the shank or stem of which passes through a hole insaid collar and engages with the rod 18. The tube 3 is formed with avertical slot 24 to allow the said thumb-screw to move up 6:, and down.l

The numeral '25 designates the jet-pipe at the upper end of tube 3. a

The operation will be readily understood. Qarburetcd air is forced fromany suitable 7o carbureting-machine to the pipe 5, and valve 20 beingopened said air will escape to the burner, where itis ignited. At thesame time the needle-valve 1) is opened to admit'alii' also from saidpipe to the tube 3 to furnish the jet or blast.

Having thus fully described my invention, what I claim is 1. In ablowpipe, the combination with the handle, the tube secured thereto, thelateral 8 pipe connected with said tube, the valve-cas ingconnccted andcommunicating with said pipe, the needle-valve located in said casingand the burner connected with the casing, of the vertically-movable rodlocated in said 8; tube, the circular valve at the upper end of saidrod, and means for operating the same, substantially as described.

2. In a blowpipe, the combination with the handle, the tube connectedtherewith, the laton oral pipe connected with said tube, the valvecasingconnected with said pipe, the needle valve, and the burner connectedwith said casing, of the vertically-movable valve located in said tube,the rod connected therewith, the collar on said tube, the thumb-screwpassing therethrough and through a vertical slot in said tube andsecured to said rod, substantially as described.

In testimony whereof I' have hereunto set for my hand in presence of twosubscribing witnesses.
